Answer:
y=13
Step-by-step explanation:
Because m=slope=
13 − 13/11 - 13 = 0
therefore we use y=13 because the y value is always the same, and the two point have the same y value.
The table above gives population and employment numbers for a hypothetical country. What is the unemployment rate in this country? Round your answer to the nearest whole percent if necessary
WHAT IS THE ANSWER HELP lol
Answer:B. 17%
A.83%
B.17%
C.20%
D.10%
The unemployment rate in this hypothetical country is equal to 17%.
How to calculate unmployment rate.First of all, we would determine the percentage of people that are employed and then subtract this percentage from the total percentage of 100%.
The table below gives the complete information about the population and employment numbers for a hypothetical country:
Total population = 1,000Total population over 16 years of age = 800Total labor force = 600Total employment = 500Mathematically, employment rate can be calculated by using this formula:
[tex]Employment\;rate = \frac{Employed}{Labor\;force} \times 100\\\\Employment\;rate =\frac{500}{600} \times 100\\\\[/tex]
Employment rate = 83.3 ≈ 83%.
For the unemployment rate, we have:
Unemployment rate = 100 - 83
Unemployment rate = 17%.

A Web music store offers two versions of a popular song. The size of the standard version is 2.9 megabytes (MB). The size of the high-quality version is 4.6 MB. Yesterday, the high-quality version was downloaded three times as often as the standard version. The total size downloaded for the two versions was 4342 MB. How many downloads of the standard version were there?
Answer:
260 Downloads
Step-by-step explanation:
s = number of standard downloads
3s = number of high-quality downloads
2.9s + 4.6(3s) = 4342
2.9s + 13.8s = 4342
16.7s = 4342
s = 260
The standard version was downloaded 260 times and the high-quality version was downloaded 780 times.

9(8-x) =3x
Answer:
x=6
Step-by-step explanation:
I don't know if you are solving for x but x=6
9(8 - x) = 3x
Multiply 9x8 and 9-x
72 - 9x = 3x
Add the 9x
72 = 3x + 9x
Add 3x+9x
72 = 12x
Divide 12x/12 and 72/12
12x/12 = 72/12
x = 6
Answer:
9(8 - x) - 3x
⇛72 - 9x - 3x
⇛72 - 12x
⇛12x = 72
⇛x = 72/12
Therefore, x = 6. Ans.

Certain drug is used to treat asthma in a clinical trial of the drug 24 of 282 treated subject experienced headaches based on the data from the manufacturer the accompany calculator display results from a test of the claim that less than 11%
Answer:
See below
Step-by-step explanation:
The test is one-tailed (left-tailed in this case) because you are trying to prove that the true proportion is less than the proposed proportion of 11%
The test statistic, z, is given to us as z=-1.34 when rounded to 2 decimal places.
The p-value, p, is given to us as p=0.0908 when rounded to 4 decimal places.
The null hypothesis is [tex]H_o:p<0.11[/tex] because the original claim was that the proportion was less than 11%.

How do I factor an equation in the Ax^2+Bx+C form, if A= 2, B= 15, and C= -27. I tried using the x method but I don't think it's the right way.
Answer:
(2x - 3)(x + 9)
Step-by-step explanation:
A = 2
B = 15
C = -27
when we plug these numbers into the equation (Ax^2 + Bx + C) we get
2x^2 + 15x - 27
using the "X" method we have to multiply the A term and C term together
so -27 x 2 = -54
so we have to find factors of -54 that also add to the middle term, 15
- 3 and 18 add to 15 but also multiply to -54 so we can add these numbers into the X (refer to drawing)

What is an equation of the line that passes through the point (-7,-6)(−7,−6) and is parallel to the line x-y=7x−y=7?
Answer:
y = x + 1
Step-by-step explanation:
The gradient of a line can be defined by the equation:
m (gradient) = (y1 – y2 ) ÷ (x1 – x2) ----> "1" and "2" should be in subscript
For (-7,-6) we use x2 and y2 (because this point can be anywhere along a line):
x2 = -7, y2 = -6
Plug these values into the formula above:
m = (y-(-6)) ÷ (x-(-7))
m = (y+6) ÷ (x+7)
At this stage, the equation can't be solved as there are two unknowns. Therefore, the gradient must be found another way. Two lines are parallel if they have the same gradient - in their y=mx+c equations, m will be equal.
x - y=7 is the line alluded to in the question. Rearranging this equation into the line equation format gives:
y = x-7 ---> The gradient (coefficient of x) is 1.
Therefore, the gradient of the other parallel line must also be 1.
This can be substituted into the previous equation to give:
1 = (y+6)÷(x+7)
x+7 = y+6
x+1 = y
Therefore, the answer is y=x+1

Thereisalinethatincludesthepoint(0, 19)andhasaslopeof 10/9 . What isitsequationin slope-intercept form?
Answer: y=(10/9)x+19
Step-by-step explanation:
The slope intercept form is y=mx+b, where m is the slope and b is the y-intercept (the value of y when x=0).
We are given the slope, m:
y=(10/9)x+b
To find b, enter the given point (0,19) and solve for b:
y=(10/9)x+b
19=(10/9)*(0)+b
b = 19
So we have y=(10/9)x+19

A store sells two sizes of bottled water. Size A is 32 fluid ounces (f1 oz) for $2.56 and Size X is $4.80 for
48 fluid ounces. Which is the better buy? Justify your answer.
#size A
32fluid ounces=$2.561 fluid ounce:-
[tex]\\ \sf\longmapsto \dfrac{2.56}{32}=0.08[/tex]
#Size X
48 fluid ounces=4.80$1 fluid ounce
[tex]\\ \sf\longmapsto \dfrac{4.80}{48}=0.1[/tex]
We can see
0.08<0.1
So Size X is better to buyhow to solve 2(10 -6x)=x -8x
Answer:
x=4
Step-by-step explanation:
2(10 -6x)=x -8x
Multiply 2*10 and 2*-6x
20-12x=x-8x
Add 12x
20=x-8x+2x
Combine x and -8x
20=-7x+12x
Combine -7x and 12x
20=5x
Divide 5x/5 and 20/5
4=x
So x=4
The solution to the equation is x = -4.
To solve the equation 2(10 - 6x) = x - 8x, you can follow these steps:
1. Distribute the 2 to the terms inside the parentheses:
20 - 12x = x - 8x
2. Simplify the expressions on each side by combining like terms:
20 - 12x = -7x
3. Move all the x terms to one side and the constant terms to the other side by adding or subtracting:
-12x + 7x = 20
Simplifying further, we have:
-5x = 20
4. Divide both sides of the equation by -5 to solve for x:
x = 20 / -5
x = -4
Therefore, the solution to the equation is x = -4.

find a series expansion for pi using the Maclaurin expansion for arctan(x) and the fact that tan(pi/4)
Recall that for |x| < 1, we have
[tex]\displaystyle \frac1{1-x} = \sum_{k=0}^\infty x^k[/tex]
It follows that, for |-x²| = |x|² < 1, or just |x| < 1,
[tex]\displaystyle \frac1{1+x^2} = \frac1{1-(-x^2)} = \sum_{k=0}^\infty (-x^2)^k = \sum_{k=0}^\infty (-1)^k x^{2k}[/tex]
Taking the antiderivative of both sides gives us
[tex]\displaystyle \arctan(x) = C + \sum_{k=0}^\infty \frac{(-1)^k}{2k+1} x^{2k+1}[/tex]
where C is a constant, which we determine to be 0, since taking x = 0 on both sides makes the series vanish, while arctan(0) = 0 since 0 = tan(0). So
[tex]\displaystyle \arctan(x) = \sum_{k=0}^\infty \frac{(-1)^k}{2k+1} x^{2k+1}[/tex]
Since tan(π/4) = 1, it follows that π/4 = arctan(1), so in the series we replace x = 1, then solve for π :
[tex]\displaystyle \arctan(1) = \sum_{k=0}^\infty \frac{(-1)^k}{2k+1} 1^{2k+1}[/tex]
[tex]\displaystyle \frac\pi4 = \sum_{k=0}^\infty \frac{(-1)^k}{2k+1}[/tex]
[tex]\displaystyle \pi = \sum_{k=0}^\infty \frac{4(-1)^k}{2k+1}[/tex]
[tex]\pi = 4 - \dfrac43 + \dfrac45 - \dfrac47 +\cdots[/tex]
If y varies directly with x and y=12 when x=3, find y when x=1.
Answer:
y = 4
Step-by-step explanation:
y ∝ x
y = kx (k is constant)
when y = 12 and x = 3
y = kx
=> 12 = k*3
∴ k = 4
when x = 1 and k = 4
y = kx
= 4*1
= 4
